Title: Burning controller
Inventor: MURASHIGE SHINICHI
IPC: F23N1/00
Filed: 1980-03-19
Abstract: PURPOSE: To decrease a difference in a response property due to a difference in a position of an actuating point by changing a deviation per unit temperature, by a method wherein, in a proportional control system combustion controller, an output of a PID control circuit, inputting a temperature deviation signal, is cuased to feed back.  
     CONSTITUTION: A burning controller BC, consisting of a control circuit CC and a load circuit LC, compares a hot water temperature, detected by means of a thermister TH, with a hot water temperature set by means of a temperature setter TS, and regulates a proportional valve PV according to the resulting deviation to adjust a gas feed amount to obtain hot water maintained at a desired temperature. The burning controller BC provides with a PID control circuit (a) which generates a signal for actuating the PID according to the deviation between the hot water temperature so detected and the hot water temperature so set. A resistor 10 is then connected in series to a bridge circuit forming an input circuit for the PID control circuit (a), and the output of the PID control circuit (a) is caused to feed back to the connecting point through a resistor 11. This enables a voltage applied to the bridge circuit to be proportioned to the output of the PID control circuit.
